DUST-REMOVEFI AND AIR-PURIFIER- Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed April 21, 1906. Serial No. 313,087-

Air-Purifiers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beingjhad to the accompanying'drawings, and to the: figures of reference marked thereon, which form a part of this specification. I

This invention relates to a dust-remove and air-purifier; and it consists in the construction and arrangement of partshereinafter fully set forth, and pointed out partic- 1 ularly in the claims.

The object of the invention is provide simple and efficient means for'separatin g dust,

smoke, and other foreign substances from the air and maintaining the air in circulation throughout a room or building, the device being also applicable for the removal of care caloric current or flue-gases bon from 1. from furnaces.

Fig. 5 is a fra'gmentaryview in perspective,

showing one of the arms which control the with the interior of the c linder through an opening in the end thereo and having at the other end an air discharge or outlet pipe 3. When used for the purpose of removing dust and impurities from the air in a building, the intakeipe 2 will be turned downwardly and the out et-pipe 3 will be turned .u wardly, so that the cleansed air maybe disc arged into the room and the dust-laden and impure air may be drawn into the separator from a point ad'acent to the floor.

- lExtending lon 'tudinally of the separatjoumaled at its 0 posite ends-in suitable bearings is a shaft 4, aving aret The above object is attained by the structure illustrated in the accom-,

; of the cylinder and carry the arms 16.

Fig. 2 isa Fig. 4 is a transj verse section as on dotted line 4 4 of Fig; 2.

on one end a pulley 5, through the medium of which it maybe rotated from any suitable source of power.', Fixed to the shaft 4 are aplurality of spiders 6, having radial arms 7, to which are secured the ion itudinally-extending blades 8, forming a an within the cylinder parallel with the axis thereof. The spiders are so positioned upon the shaft as to cause the blades to stand spirally, whereby by the rotation of the fan formed by theblades and spiders the air will be carried longitudinally through the separating-cylinder and caused to whirl ra idly therein. Located on opposite sides 0 the separating-cylinder e dust-receiving tubes 9, which extend longitudinally and which communicate with the cylinder through the longitudinally-extending openings 10, through thewall thereof. The rear ends of the tubes 9 are closed, as shown at 11 in Fig. 3, while the-forward ends thereof are connected by means of the pi es 12 with the dust-discharge pipe 13, WlllOll may be carried to any suitable receptacle.

Controlling the openings 10, which extend longitudinally of these arating-cylinder, are the dampers 14, whic are hinged in said openings upon the longitudinally-extending rods 15, whose ends project through the e1131d Y swinging said arms the rods 15 are actuated to open and close the dampers accordingly as conditions may require. The outer ends of the arms 16 lie under a graduated circlebar 17, (see Fig. 5,) having a. curved slot 18 therein, through which passes a threaded stem 19, that is secured in the end of said arm and receives the knurled nut 20, which may be screwed against the face of the circle-bar to lock the arm 16 against movement. The scale 21 on the circle-bar indicates the extent to which the damper is opened.

In the operation of this apparatus the rotation of the shaft4 will cause the fan-blades to expel the air from the cylinder, thereby drawmginto the cylinder through the pipe 2 a' current of air which is directed centrally therein and which. by the action of the rotary blades is thrown outwardly from the center, whereby any foreign particles of reater specific gravity than the air will be driven outwardly by centrifugal force against the wall of the'cylinder and caused to whirl around within the cylinder in contact with the wall thereof. By this arrangement the dust particles and heavier foreign substances are directed by the inwardly-extending dampers 14 through the openings 10 into the dust-receiving tubes 9, through which said particles are carried by a current of air which also passes into said tubes outwardly into the dust-receiving pipe 13,- while the main portion of the air freed from the dust and heavier foreign substances is discharged into the room through the pipe 3. The operation of the machine in this respect is so sensitive that gases of greater specific gravity than air may be separated therefrom and the purified air discharged into the room while sald gases are conducted through the tubes 9 and pipes 12 into the discharge-pipe 13.

By the use of this ap aratus smoke may be separated from the ca oric current from furnaces by receiving said current into the pipe 2 and discharging it into the stack through the pipe 3, in which case the apparatus will be located in a vertical position, the carbon and heavier gases being separated by the rotary fan from the heated air and directed na'led therein and extending longitudinally thereof parallel with the axis of said cylinder, a dust-receiving tube exterior to the cylinder, the Wall of the cylinder having an opening communicating with said tube; means for regulating said opening, anintake-pipe communicating centrally with one'end of said cylinder having an opening in the Wall thereof, a dust-tube communicating with said opening, a dam er for directing the dust from the cylin er into said tube, a discharge-pipe leading from the forward end of the dust-tube, an intake-pipe communicating centrally with the fan at one end of the cylinder, and an air-discharge pi e leading from the o posite endof the cylin er.

3. In a ust-se arator and air-purifier, the combination of tl ie cylinder, a fan journalcd in the cylinder having s iral blades, a lurality of dust-tubes para lel with the cy inder, the wall of the cylinder having openings communicatin with said tubes, means for directing the ust through said openings, a common dust-discharge ipe with which the dust-tubes are connecte an air-intake and an air-exhaust pipe communicating respectively with the opposite ends of the cylinder.

4. In a dust-se arator and air-purifier, the combination of tl fe cylinder, a fan journaled in the cylinder having spiral blades, a relatively small intake-pipe communicating centrally with one end of the c linder, a relatively large discharge-pipe eading from the opposite end of the cylinder, dust-tubes extendm longitudinally of the cylinder, the wall of t e cylinder having openin s which communicate with said tubes, movab dampers controlling said openings, means for moving said dampers, and a discharge-pipe communicating with the discharge ends of the dust-tubes.

In testimony whereof I sign this specification in the presence of two witnesses.
